Help!

Just received an extractor modell b200 from Rimini Lambretta and it doesn't fit My Flywheel. The bolt and tool base are both too large. Rimini stated the tool should work with all LD models. I've added pictures and am thankful if anyone has any advice!

If it's a flywheel extractor designed to fit the Li/Tv/SX/GP models, it should fit the Ld flywheel - the threads are the same. I see the flywheel nut is still in position in your photo - you will need a thin-walled 19mm socket to remove that as a first step, and a flywheel holding tool.

What flywheel is that? It looks different to any Ld, D I've ever worked on. It looks as if there is some sort of advance, retard mechanism.

It's a Filso, with external bobweights, spring and plastic stop ring removed. All Italian LD models from about 1955 onward used flywheels with advance/retard mechanisms (Filso or Marelli) - maybe you've only worked on the early stuff - or French LDs?

Same filso flywheel as my ld. . Sorry if its obvious but you do know you have to remove the nut and washer out of the middle first? Then the extractor will screw in and then screw the bolt in to pull it all out

Thanks for the reply's. I just need to find a socket thin enough to get at the bolt.

Any brand you know of that is thin enough? Im struggling

I had to grind a standard socket down a bit to get it to fit inside, but there are thinner walled ones out there

I got the flywheel bolt off with a filed down socket wrench, thanks for the tip.

Problem remains. The extractor won't thread.

Get a caliper and measure the diameter of the flywheel thread and the diameter of the "valleys" of the extractor thread. They should be close with the extractor thread being a bit smaller.

I have a had a few poorly made extractor tools where the starter thread was not formed properly. A touch up with a small file fixed it.

If anyone has used a hammer to try and "shock" the flywheel off, they may have damaged the threads. See if you can feel or see any damage or peening. You may be able to CAREFULLY grind down the damaged threads with a dremel so the extractor can reach the good threads.

Thanks JB: I bought a new one from Cambridge Lambretta and it went on perfectly, treaded correctly with a bit of elbow grease needed to get it in.
